I'll leave with a interesting video a friend sent me the other day. It's a clip from a program called Wallace & Gromit's World of Invention Episode 1 Preview - BBC One

In Holland we meet the brilliant sculptor Theo Jansen as he shows us his latest amazing contraption, the Animaris Siamesis - a huge insect-like structure that moves independently and gracefully with the wind.

Around the 0.50 mark is where it gets interesting. I'm both amazed and a little disturbed by Theo......LOL
